About the standby mode
The surround amplifier enters standby mode
automatically (the S-AIR/STANDBY

standby mode or wireless transmission is
deactivated.
The surround amplifier is turned on
automatically (the S-AIR/STANDBY
indicator turns green) when the system is
turned on and wireless transmission is
activated.
For details, see "Troubleshooting"
(page 11).

amplifier to change the power mode.
Preventing transmission

and their IDs are the same as yours, your
neighbors could receive the sound of your
S-AIR main unit. To prevent this, you can
identify your S-AIR products by performing
the pairing operation.
